The main Elephant & Piggie series by Mo Willems spans 27 entries, including the 25 original picture books published between 2007 and 2016 plus two compilation volumes released in 2025. The books follow Gerald and Piggie through everyday situations that young readers can relate to: playing outside, sharing, feeling sad, and saying goodbye.
Each book is built around a single concept or emotion, told through dialogue between the two friends. Gerald tends to worry and overthink, while Piggie approaches everything with enthusiasm. The contrast between their personalities drives the humor and the heart of every story.
The final original entry, The Thank You Book (2016), was designed as a farewell to the series and became one of the most emotionally resonant picture books of the decade.
